Problem with 2.6.23.1-grsec and MySQL 5.0.32-7etch1

[Hal9000]

Hi!
I have been happily using the 2.6.21.6-grsec kernel with my debian etch machine, and yesterday I updated the kernel with a 2.6.23.1 using the latest grsec patch from October 12th, and since I rebooted I am experiencing a strange problem where the MySQL server would go down. It did four times in the past 24 hours (since I rebooted). This never happened before.
MySQL is version 5.0.32-7etch1, and as the version implies, it's running on a Debian Etch machine (32 bit). The kernel configuration basically remained the same.
In the syslog I can see this:

Any ideas?

[Hal9000]

By the way, I just repaired that crashed table.
But I don't think it was the root cause of the problem, or was it?

the problem is still there:

By the way, I just repaired that crashed table.
But I don't think it was the root cause of the problem, or was it?

a damaged DB can cause a crash if the parser code isn't carefully written, but that sounds unlikely in this case. can you decode the backtrace to see what symbols the addresses correspond to? or at least send me the mysqld binary (i think the top of the backtrace falls in the main executable)? other than that, you could try running without SANITIZE and see if it helps.

[Hal9000]

sorry, but as this is a production machine i had to revert to the old kernel, so i cant do any backtrace now.
do you need the binary log files, or just the mysqld executable binary? and where should i send it/them to?

you don't need any particular kernel for a backtrace , just a coredump and gdb. but i take it that didn't happen (mysql catches sigsegv), so the alternative is to manually decode the addresses into symbols, for that i need the binary itself (the logs you posted already contain the address info). as for where to send it to, my email address has always been on the PaX homepage . one more thing, if the binary is stripped, i'll need the debug symbols, i think/hope that debian maintains them in a separate package that you can download (or just tell me which exact mysql package it was and i'll try to find it).

[Hal9000]

I am using this package: http://http.us.debian.org/debian/pool/m ... h1_all.deb
and this is the source package:
http://packages.debian.org/source/etch/mysql-dfsg-5.0

Tell me how i can help you more

[Hal9000]

any news on this?

[bugboom]

Out of curiosity, does the virtual memory usage(displayed by "ps aux" in the VSZ field and "top" under the VIRT column) of MySQL increase over time, to far higher than it should be?

[Hal9000]

as it's a production machine and i reverted to the previous kernel to fix the problem, i cannot try to reproduce right now...

[PaX Team]

any news on this?

i'm still debugging a few problems that are all possibly linked, i'll let you know when there's something to test.

[PaX Team]

any news on this?

i've fixed the 'bad page state' error, i can't say if your bug is related to it, but if you have the time, you could give the new test patch a try.

[Hal9000]

ok, i will try over the weekend.
just in case the problem still occurs, is there a way i can get more information for you before i reboot the kernel with the older kernel?

[Hal9000]

ok, i finally retried upgrading the kernel from my 2.6.21.6 to the latest 2.6.23.12 with latest grsec patch (from december).
the problem seems to have disappeared.
